if...else in one line of Python
if-elseThe statement works in such a way that if the condition is true, then ifthe statements following it will be executed, otherwise elsethe statement after it will be executed.
if-elseStatements usually require a maximum of 4 lines of code to work. Nevertheless, sometimes, in return statements and other nested functions, it must be compressed or condensed to make it readable and convenient.
if-elseThis tutorial will help you condense the statement into a simple single-line statement
in Python .
[if_true] if [expression] else [if_false]
This is if-elsea compressed or condensed form of the statement. Where [if_true]is the statement that will be executed if the expression is true and if it is false [if_false].
For example,
i = 1
j = 5
min = i if i < j else j
print(min)
Output:
1
if-elseThere are several alternatives
for concise statements. We can also use a similar tuple approach.
Syntax for direct methods using tuples:
(If_false, if_true)[test_expression]
This tuple method takes two expressions in the form of a tuple against a text expression. If the expression is false then the first expression will be executed else the second expression will be executed.
For example,
a = 1
b = 3
print("smaller no. is:")
print((b, a)[a < b])
Output:
smaller no. is:1
We can also use a dictionary to achieve the same result.
Syntax for direct methods using dictionaries:
({True
i, False: j}[i < j])
Here, a Dictionary is used to select an item.
For example,
i = 1
j = 2
print({True: i, False: j}[i < j])
Output:
1
